lteferring'to the drawings in detail l denotes the engine of an automobile, 2 the exhaust manifold of the engine, 3 the engine hood, et the Windshield, 5, the 'body of the automobile, 6 the fan shaft, 7 the fan and 8 a discharge pipe extended rearvvardl' from the exhaust manifold 2. rlhe foregoing elements are of lrnownconstruction, with this exception that the fan shaft 6, is extended rearwardly from its bearing 9 and carries a drive pulley 10 for a purpose to be presently referred to.

Coacting with the Windshield d, as Well as l being fixedly secured thereto, for the purpose of forming a hot air receiving chamber 1l, is a frame l2 of the same contour as the Windshield 4 and which carries a transparent member 13 of the same size as 'the Windshield glass. The frame l2 is positioned rearwardly with respect to the Windshield et and is fixedly secured to the latter, by a series of spaced bolts la, 'carrying Wing nuts l5. Mounted on the bolts 14 and interposed between the frame l2 and windshield a are resilient spacingmembers or collars i6. 'llhe frame l2 has secured to the outer edge there- 'isA of, as Well as being coextensive with the end and bottom edges .thereof a strip of re silient material, indicated at l?, *which projects forwardly of the frame l2 and has the projecting portion thereof enlarged, as at 18. The enlarged portion i8 of the strip 17,. abuts against the Windshield d and provides the lower and end Wall of the chamber ll. The strip l? further provides what may be termed a resilient 'sealing means between the opposed faces of the frame l2 and Windshield 4. 'lhe top of the frame l2 abuts, against the cross support i9 for the top of the windshield 4. The wing nuts 15'provide means for tightly clamping, in connection with the collars 16 and strips 17 the frame 12 to and rearwardly of the windshield 4.

Referring to Figures 1 to 6, the heating attachment includes a heated air conducting pipe 26 which is vertically disposed and extends through a keeper 27 attached to the inner face of the lower support 28 for the windshield 4. The pipe 26 1n proximity to its up er end and below the support 28 is pillovl ed with a manually operated controlg valve 29. The pipe 26 extends through the bottom portion of the strip 17 in proximity to one end thereof and opens into the chamber 11, as indicated at 30 and clearly shown in Figures 3 and 4. Surrounding the discharge ipe 8, as well as being connected therewit in any suitable manner and spaced therefrom is a tubular casino' 31, forming in connection with the discharge pipe 8 an air heating chamber 32. By way of example the casinor 31 is shown as havin its inner face, at each end thereof, threade for engaging with the coupling members 33 and these latter are flanged as at 34. The casing 31 abuts against the flanges 34 and l the coupling members 33 provide means for closing each end of the chamber 32. As shown the discharge pipe 8 is of L-shaped contour and the casing 31 corresponds to the shape of the pipe 8. It is to be understood that the pi 8 can be of any shape desired, but the casing 31 will conform to the shape of said pipe. The casing 31 at its forward end is provided with an intake nipple 33` for cool air and said casing 31 in proximity; to its rear end and on its top is formed wi an outlet nip le 34', to which the lower end of the hot air vconducting pipe 26 is vconnected.

Secured to the rear face of the su port 28 by the keeper 35V and leading from t e chamber 11, is a pipe line referred to generally by the reference 36 and which acts as a hot air discharge pipe for the chamber 11 and further acts as a cool air intake pipe. The upper terminal portion of the line 36 is indicated at 37, and is formed with an outlet 38, which is controlled by a valve 39. The pipe line 36 below the outlet 38 is formed with a cool air inlet opening 40 with which communicates a cool air intake pipe 41 in which is arranged the valve 39. A stop 39 is provided for the valve 39 and which in connection with the latter closes the intake 40. The valve 39 is mounted on a pivot bar 42 which extends from the intake pipe 41 and carries a handle member 43', to -provide for the manual o eration or shifting or adjusting of the va ve 39. The various positions of the valve 39 are illustrated in dotted lines in Figure 6. The pipe line 36 extends forwardly with res ect to the conducting pipe 26 and opens urto a suction device 43 memes as at 44. The shaft ofthe suction device is indicated at 45, and carries a ulley 46 which is operated from a belt 47 iven from the pulley 10. The suction'device is supported rom the forward end ofthe engine 1. The pipe line 36, not only provides means for the ischarge of hot air from the chamber 11, as Well as a cool air sup ly line, but further acts in connection with t e suction device 43 as a suction pipe. Extended from the suction device 43 and connected to the nipple 33 is a cool air sup ly pipe 46 for th chamber 32. The circu ation can be reverse by changing the direction of operation of' the device 43.

B setting up the attachment with the con ucting pipe 26, the pipe line 36, suction device 43, supply pipe 46 and with the pipes 26 and 46 communicating with the chamber 32 a circulation of hot air is had throu h the chamber 11 thereby heating the winds ield in a manner to prevent the accumulation of frost and moisture thereon. The air suppllied to the chamber 32 is heated from the ex aust from the engine 1 and the circulation of the hot a ir through the chamber 11, 'as well as the sup ly of cool air to the chamber 32 is carrie on during the o eration of the engine, due to the fact that t e suction device 43 is operated from the fan shaft 6 on the travel of the automobile, or when the motor is in o eration.

In the form shown in i re 7 the pipe line Z156 s dislpensed with rnb the cool air is sup ie totiecamer3, asup i 33? which extends forwardly fronli3 the ing 31 and is provided with a funnel-shaped o ning 34 for the rece tion of cool air directed by the fan 7. In t e form shown in Figure 7 the suction device 43 is dispensed with as well as its operating means, when usin the form illustrated in Figure 7, the modified construction of Windshleld shown in Figure 4 is employed. The windshield shown in Fi re 4, is of the same construction as the crm shown in Figure 3, with the exception that the bottom rail or member of the frame 12, which is indicated at 20, is formed with a air of openings 21 controlled by ventilatmg slides 22, which are carried by casings 23 secured to the rear face of the bottom rail or frame member 20. The holdfast devices for securing the casings 23 in position are indicated at 24. The slides 22 normally close the openings 21 and are oppositel disposed with respect to each other an each of which is formed withl an angularly dis osed end 25 to facilitate the shifting the side when desired. The openings 21 and slides 22 are provided so that the hot air from the chamber 11 can be discharged into the interior of the automobile for heating the car. Otherwise than that as stated, the form shown in Figure 7 is the same as that illustrated in Figure 1.

it is thought the many advantages of a heating attachment iior Windshields, in accordence `with this invention can be readily understood, .and although the preferred embodiments of the invention are as illustrated and described, yet it is to be understood that changes in 'the details of construction can be had which will tall within. the scope of the invention as claimed.
